NATALIE GREFENSTETTE | Postdoc

SANTA FE INSTITUTE

Natalie Grefenstette has always been interested in understanding life, and how it started or could start in different environments. This fascination with understanding life in the universe compelled her to study biochemistry at UCL so that she might better understand how life, at least as it is here on Earth, works. She later completed her Ph.D. in prebiotic chemistry so that she might better understand the chemical processes present at the start of life on Earth. She is interested in using this multidisciplinary background to help develop a deeper understanding of the organizing principles of biology and its very nature, and gain better understanding of life’s emergence on Earth and elsewhere, and how to detect life, in any chemical form it might take. 

COLE MATHIS | Postdoc

UNIVERSITY OF GLASGOW

Cole Mathis is a Post-Doctoral Researcher and Team Leader of the Artificial Life team in the Cronin Group at the University of Glasgow. His research focuses on connecting theory and experiments to detect and characterize abiotic and biological chemical mixtures. His primary research interests are the origin of Life and astrobiology. Cole received a PhD in physics in 2018 from Arizona State University, where he worked with Professor Sara Imari Walker on computational models of chemical evolution.

MAEVA MILLAN | Postdoc

NASA GODDARD SPACE FLIGHT CENTER / GEORGETOWN UNIVERSITY

Maëva Millan was trained as a physicist and earned a Master’s degree in Astrophysics and Space engineering before getting back to her first love: the origins of life! That led her to her second Master’s degree in Planetary Sciences and Space Exploration. Maëva is now a chemist, splitting her time between NASA-GSFC and Georgetown University, where she works on the search for organics on Mars with the SAM instrument onboard Curiosity. She’s also interested in the influence of minerals on organics using space extraction techniques, such as pyrolysis and derivatization-gas chromatography-mass spectrometry, which she optimizes through laboratory experiments. Maëva also works on the detection and preservation of organic biosignatures in Martian and icy moon analogs in support of current and future space missions. Her favorite activities are hiking and taking pictures, especially while traveling to the beautiful landscapes where she collects samples!
